Don't forget The Italian Store on Lee Highway over by Spout Run Parkway - it's in the same shopping center as the Geriatric Giant. And there's La Union Mercado on Old Lee Highway near Arrowine and Pastries By Randolph...really really awesome picante chorizos...

Mmm. I have to confess that Italian stores around here haven't been the same since my visit to Boston. (A kingdom for some pignolis!) Thank you for the tip, though.
